There are several versions of the melody. This is transcribed approximately as sung in the video below.
Green Sally up, Green Sally down
Green Sally baked her possum brown.
I asked my mama for fifteen cents
to see the elephants jump the fence.
They jumped so high, they touched the sky
and didn't come back till the fourth of July.
Clap pattern: clap your own hands, clap partner’s right hand, your own hands, partner’s left hand, own hands, thighs
